Arata's a college student working as a "big brother for rent."
One day, he meets his new client, Junta, who looks like a total tough guy!!
Arata wonders if this is some sort of trap to get his money, but what Junta wants is for someone to pat him on the head.
Seeing someone this hot go bright red and be so vulnerable is turning Arata on... Junta's just so adorable... what's going on here!!?
